Abstract: A process for selectively plating separate surfaces of a component. The process includes electroplating a first material onto a first surface, applying a masking agent to the component, tumbling a plurality of components to remove the masking agent from a second surface, electroplating a second material onto the second surface, the masking agent preventing electroplating on the first surface, and then removing the masking agent from the first surface.

Abstract: A rough and porous coating is applied by spraying and metallurgically bonding to a bearing member. The coating is preferably of a strong and thermally conductive material, such as aluminum-bronze, with the coating having interstices, such as cavities, undercuts and craters to provide a porous material. A lamina section of interwoven solid lubricant threads and bondable threads in an adhesive is applied to the coating.

Abstract: A rough and porous coating is applied by spraying and metallurgically bonding to a bearing member. The coating is preferably of a strong and thermally conductive material, such as aluminum-bronze, with the coating having interstices, such as cavities, undercuts, and craters to provide a porous material. An adhesive-solid lubricant formulation is then applied to the coating. The adhesive-solid lubricant formulation fills the coating interstices. The adhesive-solid lubricant formulation is cured for the required time at the required temperature to form a low-friction bearing surface layer.
